Morning looking for torques and valve clearance on a fiat 640, thanks

ask your local fiat dealer

Topic about download

sounds like the valve clearances are incorrect if your engine has got adjustable valve clearances check that 0.40mm inlet 0.50mm exhaust but the engine changed in 1999 to hydraulic valve lifters and when you refit origional folowers you should compress them to remove the old oil or the new refubished cyl head/valves will have no compression because the valves are not seating

On all Fiat overhead cam engines which use bucket followers and shims then almost without exception the valve clearances should be:

0.50mm +/- 0.05mm - EXHAUST
0.40mm +/- 0.05mm - INLET

Torque settings mains bigends flywheel cyl head valve clearance na 20 nissan engine please

hi have a look on this page it tells you in newton meters http://www.howtomendit.com/answers.php?id=262505
hope this helps ivan

Spark plug gap should be 0.9mm, valves -inlet (cold) 0.30-0.40 mm and outlet (cold) - 0.40-0.50 mm.

valve clearance is .014 inch for intake and exhaust with engine warm.
head torque it 21 ftlbs, then 44 ftlbs, then loosen all, torque to 89 inchlbs, then to 21ftlbs, then mark and turn the bolts an additional 60 to 65 degrees.
cyl head sub bolts torque 80 to 100 inchlbs.
thanks.
